Zantedeschia plant named &#39;edge of night&#39;

ABSTRACT

A new and distinct Zantedeschia plant named ‘Edge of Night’, having striking, extremely dark purple, almost black, spathe, leaf margins and petioles.

[0001] The present invention relates to a new and distinct cultivar of Zantedeschia hybrid and given the cultivar name ‘Edge of Night’. Zantedeschia is in the family Araceae.

[0002] This new cultivar was discovered in a large shipment Zantedeschia ‘Schwarzwalder’ (U.S. Plant Pat. No. 11,001). It was found by Frank Patterson in West Linn, Oreg.

[0003] This plant is characterized by the following:

[0004] 1. Extremely dark purple, almost black, flowers or spathe.

[0005] 2. Very dark petioles and leaf margins.

[0006] 3. Leaves spotted white and pink.

[0007] 4. Excellent vigor.

[0008] This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by tissue culture using standard micropropagation techniques with side shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

BRIEF DESCRIPTION OF THE DRAWING

[0009] The photograph shows a two year old plant in flower grown in a one gallon container in the greenhouse in Canby, Oreg.

COMPARISONS

[0052] Compared to the parent plant, Zantedeschia ‘Schwarzwalder’ (U.S. Plant Pat. No. 11,001) with green leaf margins, green petioles, and green leaf veins,, Zantedeschia ‘Edge of Night’ has much darker flowers and is dark on the leaf margins, petioles, and leaf veins. 

I claim:
 1. A new and distinct variety of Zantedeschia plant substantially as shown and described.
